Log Space

This is probably going to test the graphical limits of this blog to breaking point, but I thought it would be fun to put here nevertheless. This picture is a map showing the cosmos on a logarithmic scale, all the way out from the Earth’s centre to the edge of the observed Universe with the cosmological bit at the top (naturally). 

I wouldn’t mind a pound for every time this has found itself on someone’s office wall over the years!

It was made about five years ago by a group of astronomers at Princeton and if you follow the link you can find more explanation of how it was put together, as well as various versions of the plot in different formats and resolutions, so please follow it if you can’t see the picture very well here.
